Hi there,
In general it's good for us if you click on ads - though often it's not a direct transaction - it just makes the stats look good.
We have a variety of ads - some are from affiliates - our discount partners for instance - here we get a commission on sales. With other ads - most of which which we outsource to an agency who just fills our space - you get paid depending on how many times the page on which they are on is served.
Overall though it's always helpful to shop through the ads (with our dps you get a discount too of course) and to click on them.
Thanks for asking.
